Let k, h be unknown constants and consider the linear system: -7x + 5y + 6z = -3 -19x + 9y + hz = k 6x - 2y - hz = 7This system has a unique solution whenever h is not equal to___.If h is the (correct) value entered above, then the above system will be consistent for how many value(s) of k? a. a unique value. b. no values. c. infinitely many values.

yes

Step-by-step explanation: idk idk idk idk idk SORRY LOL!

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
